I have an 8100 using software 3.0 with a 32 ipla and a pri. I have setup a test ip phone at our office using static ip(no dhcp) it works fine. But I have installed another at a customer home and used the same settings as the first phone. The firmware on that phone is 3.0.4 I end up with one way speech path and sometimes it will not release the call when it is ringing. It also reboots itself from time to time and says network busy. I have gone over the port forwarding and settings in the phone several times and can't seem to figure out what I am missing?????? The customer has cable modem and cisco valet router.. Anyone have any ideas or directions they can point me in?????

With NAT I THINK you have to have that licenced to work otherwise you should be setup on a VPN.

Hey coral thanks for the response. Do you mean ip licenses? If so I have 4 ip license on the switch.

No, I think there is an actual (seperate) license that allows for NAT tranversal on the CPU if you aren't using VPN.

hmmm ok that's news to me.. Weird that one works fine on NAT and the other doesnt.

There's no NAT License required on the SV8100 only on the UX5000

The IPLA comes with 4 licenses for IP phones as part of the package.

BTECH, when you are talking about settings being the same are you also referring to the router settings?

Thanks DN27, I was going nuts looking for a nat license..lol
dans, I do have all the settings in the switch the same, all the settings in the router the same as well. I have gone over these about 100 times now but may be missing something. I just made the 10-12 address 0.0.0.0 and changed the subnet of it to something different as recommended. I will see what this changes, if anything, but not sure what else to try.

I would strongly recommend upgrading to 4.01.

Much more stable for IP.

Wow, sorry about the goose chase. Apparently on the SV you do not need a license. I have set this up on the UX before for our phone at the house and it's a bit of a pain to pinhole all the different ports per extension that need to be unique. When adding the IP card to the system you should always zero out the original IP address that does cause issues. The phones also have to have the public IP of the network it resides at programmed looking back at your main system ( i think the system uses this to look back because by default the phone always sends it's local ip rather than the routable). Look in your phone under NAT transversal. It's take a bit to get your head wrapped around what they want you to do. The phone should be set for static as well in that house network as well and you need to do some port forwarding as well to get them to work right.

On our SV8100s NAT Traversal is license number 0031 so you may need to get that clarified locally..

Thanks Guys still banging my head. Im looking at the traversal license. Is the 4.01 upgrade free?

They are down here..

yes the 4.01 is free, it's on the ntac website.

You need a tech ID and password to access. If you work for a dealer (not a VAR) then you should have one.

Thanks Doghart I do have one and I will check i out. Just wasnt sure if it needed to be purchased or not.

quick thought.

We have Comcast out here and when you change out a router, you sometimes have to reset the cable modem for it to accept the new router.

Yep, unless you clone the MAC address of the other router.

Installed a cisco valet router at the test IP phone, reboot the cable modem.Changed 10-12 to 0.0.0.0 and the subnet to a different mask. Reboot system. Bingo the IP Test Phone that was working on a netlink router, no longer works on the cisco valet router. Thanks cisco!! Must be the router!
